Splitter as JavaBean
Hello. How can I write a class-spliiter ? and how can i use this class in my spring config ? I use camel 1.5 (because it's stable release).

Re: Camel as an OSGi service on a JOnAS 5.1.0-M3 Application Server
Hi Willem, i'll check your work as soon as i can :), and test it, thx. However, i'm not sure i'll be able to do it before the 1.6.0 release. I also saw the CAMEL-1345 report on JIRA. A way to make things become easier for the users could be to provide a Camel service when its bundle is installed and started on an OSGi gateway. It's the way i did, using iPOJO http://felix.apache.org/site/apache-felix-ipojo.html as the OSGi service manager. Cheers, Guillaume Willem Jiang a écrit : Hi Guillaume, I did some works[1] about moving the OSGI stuff from camel-core to OSGI. Current Camel 1.6 and Camel 2.0-snapshot don't check the getBundle method from the classloader to verify if the camel context is deploied in an OSGI envrionment. Please feel free to try them out.

Be aware that my work was done for integration on a JOnAS Application Server (it is the reason of the classes' names), but it can perfectly work on a standalone OSGi gateway without JOnAS (JOnAS 5 uses Felix by default).

Feel free to make comments, and if you're in need for such a service in Camel, i will be glad to include my work in the project, either as an example, or all other ways you would like to. Two examples are also provided in my project, one deeling with JMS (using the JORAM implementation) and an other one using CXF.

Re: Camel as an OSGi service on a JOnAS 5.1.0-M3 Application Server
Hi all, I just provided a test to my Camel service, in a simple OSGi gateway out of a JOnAS environment. You can check it, it may give some ideas.

Re: How to negate a Predicate?
Hi
I will add a sample to the predicate wiki page
http://camel.apache.org/predicate.html
But there is a hikup with the apache server right now, so here is part
of the source code for an unit test:
import static org.apache.camel.builder.PredicateBuilder.not;
...
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
public void configure() {
// START SNIPPET: e1
from(direct:start)
.choice()
.when(not(header(username).regex(goofy|pluto))).to(mock:people)
.otherwise().to(mock:animals)
.end();
// END SNIPPET: e1
}
};
}

But I have a few uses of .when which need to negate the Predicate, and in
those places I'm using code like the second snippet below. It works well,
and there are no compiler warnings, but it is NOT easy to read. How should
I make this code easier to read?
// take the first branch, if the regex DOES match...
choice().
when(header(foo).
regex(cheese|whey))
// take the first branch, if the regex DOES NOT match...
choice().
when(PredicateBuilder.
not(Builder.
